The dynamic parameters comprise target acceleration, target speed and target displacement, and the larger the deflection is, the larger the target acceleration, the target speed and the target displacement are selected. .
Step A4, determining the operation parameter components of each bracket according to the operation parameters, namely determining the respective rotation components and power parameter components of the oscillating bracket 22, the nodding bracket 23 and the oscillating bracket 24;
step a5, controlling the first motor 25, the second motor 26 and the third motor 27 to rotate according to the operation parameter component, so that each bracket operates according to the respective operation parameter component to compensate the deflection amount.
